Keyboard input errors

I have lost all reliable keyboard input to my G4 powerbook running on OSX 10.4. I have been able to run Tech Tool, Disk Repair and Repair Permissions. I don't have another users account and without the necessary input, I cannot sign-in as another user.
In all areas where text can be typed in, Text Edit, Apple Works, Authentication etc., if I get anything it is not close to the keystroke.
I show over 37gb available on a 80gb hard drive.

Hi, Melvin. If your keyboard is typing a lot of numerals instead of letters, press the Num Lock key (F6) to turn off Num Lock.
If that's not the problem, connect a USB keyboard to the Powerbook and see whether it misbehaves in the same way. If it does, there's a software glitch behind the problem. To confirm that, boot to a CD or DVD. If the problem disappears, software on your hard drive is definitely at fault. In that case, while booted to the CD, run the Repair Disk and Repair Permissions functions of Disk Utility to square things away on the internal HD. Failing that, an Archive and Install of OS X should put things right.
If a USB keyboard behaves properly when connected, your built-in keyboard or its connection to the main logic board has gone bad. To determine which it is, release the keyboard, flip it over onto your Tibook's wrist rests, and gently disconnect its ribbon cable from the logic board, then reconnect it. Put the keyboard back and test again. If the problem persists, replace the keyboard.

CS3 Language Keyboard Input Error

Greetings All,
I have been trouble-shooting this problem for a while, but still it is not resolved. Any help or ideas would be gladly received!
Background: We have a correctly functioning installation of Win XP, and PS CS3 Extended which appears to work normally in every other regard. No obvious errors; no crashes, no start-up complaints; nothing seemingly out of order. I use several installed languages in Windows (EngUK, Russian, Swedish, etc). All of these work normally. All of my installed fonts work correctly in every application on the system except for CS3.
There would appear to be something wrong with CS3's keyboard mapping in foreign languages. When typing with a non-English keyboard setting (any other language) and using TrueType fonts (not Open), only 'missing character' boxes appear in the artwork. The Layers menu displays the typed text correctly, but this will not appear in the artwork. If I use an old install of PS7, I can type using these same fonts correctly in any language. These layers can be imported into CS3, and these WILL display correctly on the artwork. However, the Layers menu in this case displays nonsensical characters. Ergo, I suspect that CS3's keyboard input data is errant.
Where does PS3 keep its information regarding language / keyboard layout? It is possible to edit this file(s)? Are there any other ideas regarding this problem and what might be wrong?
Thanks

Keyboard input error

hello all,
I'm having difficulty with my keyboard input.
d types out d=.
f types out 0
k types out k1
l types out l2=
; types out ;/3
delete works mostly, but sometimes types an f
caps lock also comes on by itself and also acts as return
I checked the language settings and they are all fine.
I checked SMART diagnostics, Repair Disk, Repair Disk Permissions and performed a cache cleaning.
I just updated to 10.4.9. Was running 10.4.7 and every time I tried to update the verification failed or an error was found. After running the diagnostics the update downloaded and installed successfully.
Is this something that might be able to be fixed? Or is getting a new keyboard the only option?
Any help would be appreciated.
Thanks

HttpServer error in reading buffer size via keyboard input - HELP

I've written a simple HttpServer program that reads keyboard input to construct a buffer to copy the requested file into the socket's output stream. I've done the string-to-integer conversion using BufferedReader and parse.Int. However, when I go to use the int later in the program, I keep getting the message "variable b may not have been initialized." Can anyone tell me what's missing from the code below? Thanks.
private static void sendBytes(FileInputStream fis, OutputStream os)throws Exception
     //Construct a buffer via console input
     BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
     String str;
     int b;
          System.out.println("Enter desired buffer size or CTRL-C to break.");
     //Convert entry to an integer
     do
          str = br.readLine();
             try
               b = Integer.parseInt(str);
          catch(NumberFormatException e)
               System.out.println("Invalid entry.");
     while((str=br.readLine())!=null);
     //Construct a buffer
     byte[] buffer = new byte;
     int bytes = 0;
     //Begin timing HTML page delivery
     long start, end;
          System.out.println("Timing for Web page delivery");
     start = System.currentTimeMillis();
     //Copy requested file into the socket's output stream
          while((bytes = fis.read(buffer)) != -1)
          os.write(buffer, 0, bytes);

As the message suggests, what is missing is code to initialize the variable b. The first mention ("int b;") does not initialize it. The second mention ("b = Integer.parseInt(str);") only initializes it if no exception is thrown. So it's possible for b to be uninitialized when you actually try to use it.
What do you need to change? First you need to decide what's to be done if the keyboard input isn't a valid integer. Do you have a default value in mind? If so, put that where you declare the variable ("int b = 42;"). If not, just initialize the variable to zero ("int b = 0;").

Keyboard Input Locale Error

Using Flex 3.0, targeting fp10, I'm building a rich text
editing component. Most of the keyboard input works just fine but
there is one bug.
I have a UK keyboard (and my Win Vista system language is
en-GB). When I enter text in my Flex component, however, " and @
are transposed, meaning the input works as if my keyboard were a
standard en-US. Is there a workaround for this? I don't want to
just swap the characters because our app may have users from a
number of different locales.
Thanks in advance for any assistance.

[Solved] xorg server & keyboard conf error messages after upgrade

I ran my daily upgrade (today was big, from FF to the kernel to xorg) and I was not able to login on GDM afterwards.
It's weird. The X server will start, and so will the GDM login screen. But entering the password will result in a GDM crash (I later found out that KDM and SLIM have the same issue; KDM not starting and SLIM refusing the keyboard input). So after starting an alternate console and trying to start x (startx), I have this error message:
"Th e XKEYBOARDMAP keymap compiler (xbcomp) reports:
Error: Cannot close "/tmp/server-0.xkm" properly (not enough space?)
Output file "/tmp/server-0.xkm" removed
Errors from xkbcomp are not fatal to the X server
XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect setup of xkeyboard-config.
Fatal server error:
Failed to activate core devices "
I have been fiddling with the keyboard config on xorg.conf but I'm not sure I'm getting anywhere. Also, I downgraded the xorg-server and xkeyboard config packages just to be sure.
Any clue?
Thanks!

Well... seems I didn't have any answer on this. I fiddled a bit more but I have to say that I really came to wits' end at this stage. A couple of observations though:
* I don't really understand this notion of a keyboard issue. My keyboard and its layout work properly but I will not be able to login regardless of login through GDM, KDM or Slim. Yet it's worth noting that in the case of GDM and SLIM the X server starts; I see the graphical interface, I click, etc. but when I type the trouble starts.
* I tried to check my xsessions-errors file. The file is really big under a frame buffer, and it wasn't clear to me, but I found strange that the log was reporting all sorts of attempts to start KDE. I don't exactly know what's going on.
If anybody has any clue, let me know... It's becoming very frustrating.
Thanks!

[Solved] Programs hang on keyboard input (uim-xim)

Update: I've narrowed the issue down (via trial and error) to uim-xim. If it's running, it causes this problem (in XMonad) and if it isn't, gnucash has no issues. Oddly enough, when I start uim-xim by hand after gnucash, it works fine too. Starting uim-xim by hand before gnucash results in the same issue, and so I'm inclined to believe it's either an issue with XIM implementation, or simply uim-xim. Might also be a mixture of XMonad and uim-xim, as it works fine in Openbox.
I've noticed lately that certain GTK programs (I'd list them, but I haven't paid close attention until today, where I was using gnucash) work fine until I try to input anything via the keyboard. The moment I start typing (or, at the latest when I hit the shift key or backspace key) the program will hang (without any error message). I originally assumed that this was an issue with the program - not my window manager. However, I tried one of the problem programs (gnucash) in Openbox today, and it works just fine. That leads me to assume it's caused by my configuration in some way. I have absolutely no idea where to start debugging this issue.
A bit of information:
I use UIM (in both openbox and XMonad with identical configurations), run a script for a Japanese date format in XMonad (piped to dzen), and load the same xmodmap file in both window managers. Also, I start all my window managers using CDM (Console Display Manager), but in the case of XMonad I supply a bash script instead of the binary, in order to preload certain files. Also, I use a german keyboard layout.

BlackBerry Storm2 - Japanese Text Input Error

Hi all,
I have to respond to emails on a regular basis in Japanese, and on my Storm2, I get an error when switching input languages. I get "Input system error. System is being restarted." and then I don't have a keyboard for a few minutes. I can pull the battery, but the next time I switch, the error is back. I've done a complete device wipe, reinstalled the OS, and tried 2 Verizon supported OS versions. Any ideas? I might switch back to my Tour just to get things done!

We saw your solution solved on the Blackberry Website:
Just passing the solution on for others who may have this similar issue.
Do this to turn off the Predictive Input option:
On the BlackBerry smartphone, go to Options> Language.
Below the Input Style setting, click the Show Text Input Options
Deselect the check mark for Predictive Input.

Reader Closes on any Keyboard input

Has anyone had this problem?
Reader closes on any keyboard input.
Mouse works fine. And I mean any keyboard action at anytime.
I have tried uninstalling all adobe reader apps/plugins and reinstalling the latest available version but still Reader closes with any keyboard input. Make opening password protected PDF's impossible. The "find" function unusable.
Any Ideas?

Are you trying to run your application through TextPad, or some IDE? The System.in is best for command prompt input. Trying running your program through the command prompt, and it should work fine.
I replicated your error, running your application through TextPad.

Keyboard Input Output Problems on Mac OS X

Hey guys,
I'm at college studying Java, however my teacher and the rest of the class all use the Kawa IDE, I've been using Project Builder, provided with Mac OS X. Our tutor gave us a class made up of various methods which the college designed to handle keyboard Input and Output, however when I import it I get unpredictable results. I've put it online at: http://www.lostroom.co.uk/inout/
All I'm trying to do is run a simple program;
import InOut;
class CostReckoner
public static void main(String[] args)
// Declare the variables
int quantity;
double unitCost, basicCost, vatCost, totalCost;
double vatRate = 0.175;
// Input the number of items and the cost per item
System.out.print("What is the unit cost of the items?");
unitCost = InOut.readDouble();
System.out.print("How many items in the order?");
quantity = InOut.readInt();
// Calculate the cost of the order
basicCost = unitCost * quantity;
vatCost = basicCost * vatRate;
totalCost = basicCost + vatCost;
//Output the total cost of the order
System.out.println("Cost �"+InOut.format(basicCost,2));
System.out.println("Vat �"+InOut.format(vatCost,2));
System.out.println("Total �"+InOut.format(totalCost,2));
I seem to need to press space bar after I input anything, as it doesn't recognise "Return" without it. Any ideas ??
Strange thing is it seems to work fine on the PC Kawa IDE within college. Any advice you guys could offer would be really appreciated. Send me an email at: <[email protected]> if you can help.
Regards, Gareth

Hi thanks for your help, I tried compiling the code you gave me to read the streams, however I seem to be have problems with it.
ERROR
keys.java:18: unreported exception java.io.IOException; must be caught or declared to be thrown
n=stream.read();
HERE IS THE CODE I'M TRYING TO COMPILE
import java.io.*;
public class keys {
public static void main(String[]arguments)
BufferedInputStream stream = new BufferedInputStream(System.in);
int n=0;
while(true){
n=stream.read();
System.out.println(Integer.toHexString(n));
if (n==0x30) break;// this termination condition is optional
Any ideas ??

Keyboard input performance (slow typing) on Mac OS Mavericks

After installing Mac OS Mavericks, the typing performance in Dreamweaver CC 13.1 is very slow, almost to the point of unusability.
I am aware of this discussion, however that discussion started before Mavericks was released, and there has been no acknowledgement on Adobe's part of what may be a newer issue related only to Mavericks. To further support this, I did not have any issues with keyboard input performance while on Mountain Lion.
So I'm hoping with this thread I can get some confirmation that Adobe is seeing the issue in Mavericks, and is planning a fix in the next update - which hopefully will be coming very, very soon because as I said it's almost unusable now and I saw in the other thread people are even cancelling their subscriptions over this.
Thanks,
Jeremy

Hi ,
We are happy to inform you that DW's next update is made available today. This update has a fix for the slow typing issues in DW Please install & let us know your thoughts
Code View performance improvements
The following bugs are fixed to improve the Dreamweaver performance in Code View:
Typing gets progressively slow as the number of lines of code increases.
Cursor (IP) disappears while typing and navigating in Code View.
Dreamweaver Crashes on closing a tag by entering </ in Code View.
Change the default keyboard shortcut for CTRL+LEFT to ALT+LEFT and CTRL+RIGHT to ALT+RIGHT and vice-versa.
On Mac 10.9, Dreamweaver crashes while selecting a file in File Dialog for Insert Image.
Dreamweaver displays a syntax error even if the PHP code is valid.

Keyboard input - single char

All I want is a single character of keyboard input. Is there a better (simpler) way to do this?
byte[]     bInput;
String     cResult;
bInput = new byte[1];
bInput[0] = 0;
System.out.print("\nStart FirewallChat in [C]lient or [S]erver mode? ");
try
{     System.in.read(bInput);
} catch (IOException e)
{     System.out.println("System.in.read(byte[] b) threw IOException. An I/O error occurred - maybe the input stream has been closed? Exception follows : " + e);
System.out.println(Character.toLowerCase((char)new Byte(bInput[0]).intValue()));

char c = (char)System.in.read();

Keyboard input stopped working on Solaris 11 Live x86 Toshiba R835 Notebook

I can boot, and keyboard input works for login, but does not work for xterm, terminal, Firefox, ... Mouse works for gparted and apps. It did work for 8 hrs but stopped. Any suggestions ?

I would be googling for that. E.g. see thread.
So did you update xkeyboard-config? It's tedious that you haven't had the sense yet to list which packages got updated, along with version numbers.
It's nice to see you enter here, brebs!
A few things have happened:
I just noticed that the file '/etc/X11/xinit/xinitrc' isn't present at all! It was present when I posted the thread (I think). So X didn't even start. I had to create .xinitrc in my home directory with single like 'exec xterm'. X started fine but keyboard still didn't work.
Out of nowhere, I thought of using nouveau drivers instead of Nvidia drivers. So I went ahead and switched to nouveau and bam - keyboard is working. Enabled GDM and keyboard is still working. I still would like know what went wrong with Nvidia - for educational purposes.
What more details should I provide? I'd like to have Nvidia drivers back.

Keyboard input broken on Centos 5.2

I am developing a Flex application on Windows and everything
is working fine so far.
I deployed this application on Centos 5.2 (Linux) . Most of
it seems to be working fine EXCEPT for the keyboard input part.
TextInput fields would take input from numeric-keypad and few of
the special keys but NOTHING from the alphabet-part of the
keyboard.
Any suggestions please?

I find something that is for version 904, maybe could help you
Grettings.
Cause
The error "[gsdsiConnect] ORA-0" in the oidmon.log simply means that something has gone wrong when oidmon tries to connect to the database.
Possible causes include:
a. NLS_LANG is set to a non-existant or incorrect character set e.g. NLS_LANG=american_america.NOSUCHCHARS
b. unlock.sql is not run after RepCA is run.
c. port 1521 is not used for the listener.
See also Note 260915.1
Fix
a. Set NLS_LANG to a valid character set before starting the installer. e.g. NLS_LANG=american_america.UTF8
b. Run unlock.sql.
c. Use port 1521 for the MR database listener.
